DescriptionSPIRA-TROL is a range of two-port single seat globe valves with cage retained seats conforming to ASME/ANSI standards. These valves are available in three body materials in sizes ranging from 1/2" to 4". When used in conjunction with a pneumatic or electric linear actuator they provide characterised modulating or on/off control.

SPIRA-TROL valve characteristic - options:

LEA Equal percentage (E) - Suitable for most modulating process control

applications providing good control at all flowrates. LFA Fast opening (F) - For on/off applications only.

LLA Linear (L) - Primarily for liquid flow control where the differential

pressure across the valve is constant.Important note: Throughout this document, reference has been made to the standard LEA control valve. With the exception of trim type, the LEA, LFA and LLA control valves are identical.

SPIRA-TROL valve options: PTFE seals - StandardStem sealing Bellows / PTFE - Zero emissions Bellows / graphite - Zero emissions + High temperatures Graphite packing - High temperature applications

Metal-to-metal 431 stainless steel - standard

316L stainless steel Seating Soft seating PTFE for tight shut-off Hard facing 316L stainless steel with Stellite 6 facing - for more arduous applicationsBonnet type Standard bonnet Extended bonnet for large pipe lagging or hot / cold applicationsTrim Standard Low noise

SPIRA-TROL two-port valves are compatible with the following actuators and positioners:Electric EL5600, Rotork CVL, Belimo NV and AFPneumatic PN1000 and PN9000 series PP5 (pneumatic) or EP5 (electro-pneumatic)Positioners ISP5 (intrinsically safe electro-pneumatic) SP400/SP500 (microprocessor based electro-pneumatic) SP300 (digital communications)Refer to the relevant Technical Information sheet for further details.
